how to re install os x mountain lion on my macbook pro?
My Mac book pro late 2011 was cracked. Service center said the problem is the hard drive. So I replaced a new hard drive. I replaced it with Toshiba hard drive. But I don't know how to install it. I don't have any os x disc. If I turn on my laptop and press option button, is the disk recovery is still exist? If not, how to install then? Please help. I have no idea.
MacBook Pro, OS X Mountain Lion (10.8.4)
